WINDOW.

Specification of Letters Patent.` Patented Dec. 30, 1919.

Application filed August 13, 1918. Serial No. 249,728.

To all 'whom 'it may concern.'

Be it known that I, EDMUND H. LUNKEN,

vided in the upper portion ofthe sash.

frame for the reception of the sash to give a free and unobstructedwindow opening, provision also being made for window screens locatedoutside the sash and also adapted to be pushed up into the window pocketeither to obtain access to` the sash, or for winter storage of thescreens when their use is not required.

` It is the object of my present invention toprovide in connection withsuch windows for a storm window construction.- j i Heretofore whereverstorm windows have been desired during the winter months, it has beennecessary to fit into the window opening an extra sash which has'tobesecured in place temporarily for the winter season, a matter ofconsiderable' expense, both for installation and removal. It is theobject of my present invention to provide a storm window construction inwhich the storm .window sash can be permanently mounted in the windowcasing and pushed up out of the way when not in use.

I alsoprovide in this connection a certain 4 novel construction forapplying and mounting the weather stri for the cross rails. of th'esash, which obviates the special fitting of the weather stripandwithwhich accuracy in mounting the strip so as to obtain a perfectclosure is readily attained. y

I also in connection' with the sash provide for a spring check on thesash to prevent the throwing up of the sash too rapidly against the headpiece of the casing.

These various features and otherpoints of novelty will be hereinafterparticularly pointed out and claimed.

`foi-the window screens.

In the drawing, 1 n Figure 1 is a vertical'longitudinal section of myimproved window construction.

Fig. 2 is a transverse section of a portion' of one of the side stiles,taken on the line A, A, of Fig. 1. i

Fig. 3 is a detail longitudinal section, taken on. the line B, B, ofFig. 2.

The pocket window is provided with the usual lower andupper slidingsashes l, 2, with the .meeting rails 3, 4, the sashes being mounted inside stiles 5, 6, provided with the inside and outside beads 7, 8, withthe parting bead 9 for the two sashes, sill 10 and head piece 11'.. Thesash stiles run to the top of the pocket above theiwindow opening andthe head piece closes the pocket top, while the front of the pocket isin the construction illustrated formed of corrugated sheet metal 12suitable for plastering. The outer wall of the pocket is inclosed bysheeting 13,y over which the weatherboarding` 14 or other outside finishis secured.

he window casing is also provided with the finish 15 and the sill piece16. l The sashes are provided with the usual sash cords 17,18, which runover sash pulleys 19 at the head of the stiles and to the sash n cordsare attached the usual weights in the weight box behind the stiles. fOutside of the sash' stile'sis the vsheet 'metal channel strip 20, oneon each side, to serve as a guide y Thesescreens are preferably metalframes, 2l' for the lower sash and lower frame, and 22' for the upper,with wire screening 23, 24, for the respective screens. As illustrated,a flanged strip is provided for the top rail'of the lower screen toconfine itbetween the upper the upper rail of the upper screen is formedof double thickness to lill out the opening head piece to the sill whichis provided in the Sli casing with the parting bead 28 and formed at theoutside by the inner bead 7, hitherto referred to. Mounted in thisadditional runway is an additional sash 30, provided with the sash cord31 and the sash pulley 32 at the head of the stile.

To form an effective closure of the window pocket and ordinary sash,great care must be taken that the weather stripping for the cross railsof the additional sash shall lit accurately. On the upper rail issecured the weather stripping support 33, provided with a strip' of felt34 rejecting beyond the face of the support strlp 33, and when theadditional sash is drawn down opposite the upper sash, this felt strip34 has a close bearing along the bearing strip 35. In order that anaccurate fit may be obtained, a shoulder 36 is provided for the lowerface of the strip 33, with a corresponding shoulder on the upper surfaceof the upper rail, and these shoulders will insure whenproperly cut asnug bearin of the felt 34 on the bearing strip 35. Thisweather stripfills up the space between the side of the sash and the upper crosspiece 37 of the inside bead which space. is left in order to preventthis bead from marring the outer surface of the sash when raising orlowering the same.

At what corresponds to-the meeting rails .3, 4, ofthe ordinary sash,that is the cross rail 38, there is also provided a felt strip 39 whichbears against the inlaid bearing strip 40 carried by the upper rail 3 ofthe sash 17 so that when the rails 38 and 3 are opposite each other,there shall be a tight closure between these cross rails.

lVith a pocket window construction, inasmuch as the y sashes run up fortheir full length into a pocket, it is found that with a well-balancedsash, in raising the sash the user is very apt to give such a momentumto the sash as to cause it to strike with a considerable blow againstthe head piece and the sash lights are liable to be broken by the jar,or the sashotherwise damaged. In order to check this movement and serveas a brake in raising the sashes into the window pocket, I thereforesecure in the pulley stile so as to bear against the Side front. face ofthe sash on each side, spring metal strips 41, which bear against theside members of the sash and act as a very effective brake and check themovement. As illustrated in the drawing, "I have applied these springstrips in the path of the additional sash, but for each of the othersashes similar strips may be mounted. l

In fitting the weather strips for the cross i tion as well as theentrance o withthe bearing strip with which it is to make contact.

It is thought that from the foregoing description, the use andadvantages of my 1nvention will be obvious.

It is intended to construct and ship the entire casing with all itsparts properly fitted as a single package.

Except during the winter months the additional sash will be pushed u.into the pocket and will be entirely out of) theway. The lower sash isstrippin 42 to furnish an accurate fit at the base an this 4lower sashcan be raised or lowered, and the two ordinary sashes used as usual bymerely raising the storm sash temporarily. `With the vaccurate fittingof the weather strip material and the complete el0- sure of the pocketopening by the additional sash, I have found that it is not necessary toprovide any lower storm sash, and that the single sash shown' servessufficiently to meet all the exigencies of the weather. The air spacebetween the upper sash and the additional sash very effectively reventsradiaair around the joints.

Having thus described my invention, what I claim as newand desire tosecure by Letters Patent, is y 1.
